Understanding the Hair Growth Cycle

Understanding The Hair Growth Cycle

Do you ever wonder how the hair on your scalp grows or falls out? Understanding the natural hair growth cycle is important when it comes to optimizing hair growth and reducing hair shedding. Keep reading to learn more about the hair structure and the stages of hair growth. 

Hair Structure

The hair is made up of two parts: the follicle and the shaft. Each hair on your head and body arises from a follicle, which is made of multiple layers of cells that work together for a single purpose, to produce a hair. The hair follicle is what anchors the hair into the scalp. 

Your hair shaft is the part of your hair that is not anchored to the follicle and can be seen above your scalp. It is composed of a hard protein called keratin and a protective layer called the cuticle. 

Hair Growth Cycle

The hair growth cycle is composed of four distinct phases:

Anagen: Growing Phase

Anagen is the growing phase in which the follicle is actively lengthening its hair. The anagen phase is the longest phase in the hair cycle that lasts about 3 to 6 years before hair follicles become dormant.  

The amount of time that a hair follicle stays in the anagen phase will depend on the individual’s genetics. Some people naturally have longer anagen phases than others. 

Catagen: Transitional Phase

The catagen stage is the transitional part of the hair cycle. This phase typically only lasts two to three weeks, and approximately 3% of all hairs are in this stage. In the catagen phase, the hair follicles shrink, and hair growth slows.

Telogen: Resting Phase

After the short catagen phase, telogen begins. Telogen is the resting phase in the hair growth cycle, in which the hair is released, and the hair follicle rests for roughly three months. It is estimated that 10 to 15 percent of your hairs are in this phase. 

Exogen: Shedding Phase

The exogen phase is considered to be an extension of the telogen phase. The exogen phase, also known as the shedding phase, is when the hair strands are released from their follicles and fall out. It is completely normal to shed between 50 to 100 hairs per day in this phase.
